Surface Mount Diplexer 75Ω DPLB-4254A0+ DC to 1220 MHz (DC-42, 54-1220 MHz) The Big Deal • • • • • Low insertion loss, 0.8dB Typ. High rejection, 45dB Typ. Very good return loss, 18dB Typ. 75Ω Impedance Used in DOCSIS 3.1 standard CASE STYLE: NU1620 Product Overview DPLB-4254A0+ is a Low cost diplexer with the lowpass port at DC-42 MHz and highpass port at 54-1220 MHz. Good return loss combined with high out of channel rejection makes it a ideal component in cable TV and multiband radio systems. Key Features Feature Advantages Low passband insertion loss Passband insertion loss 0.8dB ensures low signal loss through both the channels. Good Stopband rejection Co-channel rejection of 45dB ensures unwanted spurious are eliminated. Good return loss at DC-42 and 54-1220 MHz This makes signal transmission with very less reflection and well-matched with the adjacent component used in the system. Notes A.
